What are the coordinates of the image of (-6, 2) after a counter clockwise rotation of 180° about the origin?

9514 1404 393

  (6, -2)

Step-by-step explanation:

Rotation about the origin 180° in either direction negates both coordinates. The transformation is ...

  (x, y) ⇒ (-x, -y)

The image point of (-6, 2) is (6, -2).

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
